The main purpose of many medical studies is to estimate the effects of a treatment or exposure on an outcome. However, it is not always possible to randomize the study participants to a particular treatment, therefore observational study designs may be used. There are major challenges with observational studies; one of which is confounding. Controlling…
Background Unhealthy diets, the rise of non-communicable diseases, and the declining health of the planet are highly intertwined, where food production and consumption are major drivers of increases in greenhouse gas emissions, substantial land use, and adverse health such as cancer and mortality. To assess the potential co-benefits from shifting to more sustainable diets, we…
The European Prospective Investigation into Cancer and Nutrition (EPIC) is a multicentre prospective study conducted in 23 centres in 10 European countries. Here we review the findings from EPIC on the relationship between diet-related exposures and incidence or mortality from the four most frequent cancers in the European population: colorectal, breast, lung, and prostate cancer.…
Purpose: To analyze the association between salivary melatonin rhythm and prostate cancer (PCa). Materials and Methods: A total of 40 PCa cases and 41 controls from CAPLIFE study were analyzed to determine the salivary melatonin rhythm through 6 saliva samples. Amplitude (maximum melatonin peak) was categorized as low or high using the cut-off point median…
Objective: The main objective was to examine, how European Schools of Public Health (SPHs) responded to the COVID-19 pandemic through 2020, across the main activity domains of the SPHs. Methods: A cross-sectional survey based on an online questionnaire concerning the anti-COVID-19 activities from 1st March to 31st October 2020 of the 117 members of the…
Higher milk intake has been associated with a lower stroke risk, but not with risk of coronary heart disease (CHD). Residual confounding or reverse causation cannot be excluded. Therefore, we estimated the causal association of milk consumption with stroke and CHD risk through instrumental variable (IV) and gene-outcome analyses. IV analysis included 29,328 participants (4,611…
Diabetes mellitus (DM) is a complex, chronic, multifactorial, and costly health problem representing 8% of total public health expenditures in Spain. The objective of this study was to analyse the prevalence and costs of Anxiety (AX) and Depression (DP) in the Spanish working population with DM. Data were obtained from the National Health Survey of…
Objective We evaluated the temporal trend in gender ratios of first and last authors in the field of oncological research published in major general medical and oncology journals and examined the gender pattern in coauthorship. Design We conducted a retrospective study in PubMed using the R package RISmed. We retrieved original research articles published in…
Background Food biodiversity, encompassing the variety of plants, animals, and other organisms consumed as food and drink, has intrinsic potential to underpin diverse, nutritious diets and improve Earth system resilience. Dietary species richness (DSR), which is recommended as a crosscutting measure of food biodiversity, has been positively associated with the micronutrient adequacy of diets in…
Chronic lymphocytic leukemia (CLL) is preceded by monoclonal B-cell lymphocytosis (MBL), a CLL precursor state with a prevalence of up to 12% in aged individuals. However, the duration of MBL and the mechanisms of its evolution to CLL remain largely unknown. In this study, we sequenced the B-cell receptor immunoglobulin heavy chain (BcR IGH) gene…
